The Palmeiras attacker will join City in January.
Gabriel says he's willing to mix it up with where he starts on the pitch to ensure he gets some playing time.
"I prefer playing as a left winger rather than a striker, but I'm willing to play in either position," he told the Guardian.
"I'd like to think I'm a versatile player. But I will listen to the manager's opinion and advice in order to improve and adapt as fast as I possibly can."
Gabriel will join City in the January transfer window once the Brazilian league season ends.
